Z86017/Z16017 PCMCIA Interface Solution
Product Specification
Note:
POR signal is deasserted, the user must provide a clock source on the
PC_MCLK_IN pin in the range of 1-20MHz.
The external hardware can program the on-board registers and the
attribute memory by selecting the ZX6017 and pulling the EE_CS pin
High. The external hardware must set up the data to be sent to the
ZX6017 on the EE_DI pin and strobe the EE_SK pin. The first byte of
data is the address selected by the user, the second byte is the command
byte and the third byte is the data. The external hardware must provide 24
clocks in order to read or write to a location in the ZX6017 (see
Slave Interface Timing, in Appendix B).
To program the on-board attribute memory, the user must first write to it.
Accomplish this programming by writing the address location of the
attribute memory to be written (or read) in the attribute RAM data address
register at location
then writes (or reads) the attribute RAM data register
be read or written at that location.

external user’s hardware writes to register 00 and selects the clock divide
by and the override mode (if needed). The READY/BUSY pin remains
set to 0 to indicate BUSY, and a local P interrupt polarity is selected.
The user programs registers 01-05, followed by registers
user writes to the attribute memory by setting the address in the address
register
memory data. The user completes the operation by writing back to
register 00 to clear the READY/READY status.
The attribute RAM address register auto-incriments after reading
or writing to the attribute RAM data register.
